We’ve just been studying the differences between Nature and Nurture (both physical and social components) and are about to discuss in more detail the use of identical twins for studies on development. 

Here are a few resources to look into before we go through this section:

1. Mandatory: Look/read through this National Geographic article on Twins: Alike But Not Alike. It explains how science is correction the notion that identical twins are 100% the same.
2. Optional Topics to Inquire About:
   1. Twin Transfusion Syndrome
   2. Epigenetics
   3. Sperm of older males – what is being discovered about it
   4. Human Genome Study – genetic enhancements and its ethics
   5.  Read/skim through this article Identical Strangers about 35 year old identical twins who were purposely separated at birth in an effort to study twin nature and nurture influences.
   6. Behavioural Genetics – studies, ethical concerns that are ongoing
